Kylie Jenner
Kylie Jenner's raciest shoot yet? Instagram

Khloe Kardashian is standing up for little sister Kendall Jenner after the model posted a racy photo from a recent shoot with Australian photographer Russell James. The Kardashians' half-sister, who turned 18 just on old Nov. 3, shows off her braless chest in a sheer black top.

This is not the first time Jenner has shown her body off in a photo shoot, but it is certainly the most risqué. In October, the reality TV starlet became the latest face of Agua Bendita’s swimsuit collection. She shows off her slim physique in an array of colorful bikinis and one-piece swimsuits for the Colombian swimwear brand's new campaign.

Her most recent shoot, however, has caused controversy due to Jenner’s age. Khloe, 29, stood up for her, saying to critics, "I love seeing all of these haters' comments. Naomi [Campbell], Kate [Moss], Cindy [Crawford]...All fabulous models...Models and photographers take beautiful artistic images. And I don't hear you birds chirp then. Sit down and enjoy the view! #SorryNotSorry."

Meanwhile, as she makes her mark in the modeling world, Jenner has also been offered a big payday to show her body off on the big screen. At least six porn companies are said to be interested in the model such as Brazzers, and Babes and Digital Playground. One company has reportedly requested that she do a scene with female porn star Jesse Jane.
